Correct Answer: A

Rationale: The correct answer is A: Blacks. The rationale for this is that federally defined minority groups in the US typically include African Americans or Blacks. This group has historically faced disparities in healthcare access and outcomes. Russians (B) are not federally defined as a minority group in the US; Hispanics (C) and Asians or Pacific Islanders (D) are also federally recognized minority groups, but the question asks for all options that apply, and only A is explicitly mentioned in the question stem. Therefore, A is the correct answer based on the information provided.

Correct Answer: D

Rationale: The correct answer is D: control group. In this study design, Group 3 serves as the control group to compare the effects of music therapy and life review therapy on memory. The control group does not receive any intervention, allowing researchers to isolate the impact of the therapies. This helps determine if any observed improvements in memory are due to the therapies and not other factors. A pilot study (A) is a small-scale preliminary investigation, not a comparison group. A survey (B) is a data collection method, not a comparison group. A needs assessment (C) is used to determine needs, not a comparison group. Thus, the control group is essential in research to establish causal relationships.

Correct Answer: A

Rationale: The correct answer is A because when a nurse moves to a new state, they must check the new state's nurse practice act related to licensure for endorsement. This is important to ensure the nurse meets all requirements and regulations for practicing in the new state. Option B is incorrect as licensure is not automatically transferred. Option C is incorrect as certification is different from licensure, and the NCLEX-RN® is typically required for licensure. Option D is incorrect as the American Nurses Credentialing Center is not responsible for determining state licensure eligibility. Checking the new state's nurse practice act is the standard procedure for obtaining licensure endorsement.

Correct Answer: C

Rationale: The correct answer is C: security. The scenario describes measures to protect the patient records system from unauthorized access, such as requiring consent, assigning passwords, and conducting audits. Security specifically refers to safeguarding information from unauthorized access, ensuring data integrity and availability. Privacy (A) is about controlling access to personal information, while confidentiality (B) is about keeping information private. Data capture (D) refers to the process of collecting data, not protecting it from unauthorized access. In this case, the focus is on security measures implemented to protect patient records, making it the most appropriate choice.

Correct Answer: B

Rationale: The correct answer is B: educator. The nurse is providing information and teaching patients about preventing diabetic neuropathies, which aligns with the role of an educator. Educators focus on imparting knowledge and empowering individuals to make informed decisions about their health. The other choices are incorrect because: A: Change agents initiate and lead changes within an organization, not directly related to patient education. C: Managers oversee daily operations and resources within a healthcare setting, not specifically focused on patient education. D: Coordinators facilitate communication and collaboration among healthcare team members, but not primarily responsible for patient education.
